THOMAS HANSON, OF NEW YORK, N. Y.

WATER-CLOSET.

SPEGIFICATIO forming part of Letters Patent No. 255,975, dated April 4, 1882. Application tiled July 7, 1881. (No model.)

To all whom it may concern Beit known that I,THoMAsHANsoN,of New York, in the county and State of New York, have invented certain new anduse'ulImprovements in Water-Closets, of which the following is a specification.

The objectot' my improvementsis to produce a water-closet in which the basin or bowl will be effectually cleaned and from which the escape of gases will be prevented.

My improvementsconsistin the combination, in a water-closet, of a basin, a valve-chamber connected thereto, a vertically-arranged valveseat at the juncture of said basin and chamber, aslide-valve operatingin conjunction with said seat to control the escape ofthe contents of the basin, a guide for said valve, and a guideway parallel with the valve-seat and against which the guide works.

They also consist in the combination, with the basin, valve-chamber, and seat hereinabove described, ot' a slide-valve having a stem projecting from its back, a resistance-piece having a sliding connection with said valvestem, and a spring arranged between the valve and its resistance-piece for holding the valve to its seat.

They also consist in details of construction and combinations of parts, hereinafter described.

In the accompanying drawings, Figure l is a sectional side view ot' a water-closet embodying my improvements. Fig.2 is a transverse vertical section of the same, taken at the plane of the dotted line a: Fig. l; and Fig. 3 is a sectional plan thereof.

Similar letters ofI reference designate corresponding parts in all the ligures.

A designates a basin or bowl, which may be made of earthenware or other suitable material, and is shown as of elliptical form, and provided with a side outlet, A', arranged in a vertical plane.

A2 designates a pipe whereby the ushing or cleansing water is supplied to the basin. It

with the basin, or it may be connected with the basin in any other suitable manner. Itis shown as arranged for use with an overhead cistern and as communicating with the front of the basin; but it may be connected with any suitable source or head of water. It is to be `provided with a valve ot' any suitable style,

which preferably will be operated by a pullrod, B, arranged at one side, but near the front of the basin, and operating in the ordinary manner. This pull-rod is connected with an arm, C, on a rock-shaft, D, which is also provided with an arm, E. The arm Eis designed to bc connected with the valve of the pipe A2, the valve being arranged overhead.

F designates a. slide-valve arranged in a valve-chamber, G, which is connected with the basin A, and operating with an up-and-down movement in conjunction with the side outlet, A', of the said basin. Preferably there will he combined with the basin A and chamber G a valve-seat, H, of composition, metal, or other material which will not quickly corrode. This valve-seat may be arranged, as shown, so as to form one side ot' the chamber G, and the valve F will `work directly against it.

The valve F has a tubular stem or shank projecting from its back, and is held against its seat by means of a spring, I. This spring acts upon the back of the valve F, and between it and a movable resistance-piece, J, which is provided with a stem that tits in the tubular stem ofthe valve, F, and hence forms a sliding connection between the resistance-piece and valve, and so connects the resistance-piece and valve that the two will move up and down to gether. The resistance-piece J also constitutes a guide for the valve, and the adjacent wall of the valve-chamber on which it works constitutes a guideway parallel with the valve-seat. Both the valve andthe resistance-piece are guided by the edges oi' the front and back of the chamber G.

Motion is imparted to the valveF by means of an arm, K, extending from the rock-shaft D and connected with its stem. It will thus be seen that when the pull-rod B is raised the valve F is raised to open the side outlet ofthe basin A and permitits contents to escape, and that the valve controlling the flow of water through the pipe A2 is also operated to admit a quantity of water to the basin. When the pull-rod moves back to its normal position the valve controlling the ow of Water through a pipe, A2, closes, thereby shutting off the furthcrtlow of Water, and the valve F also closes the outlet of the basin tightly and prevents noxious gases from entering the basin through the outlet. The water remaining in the basin seals the valve effectually.

At the back ot' the basin A is an overliowoutlet, A3, which communicates through a pipe or conduit, L, with an overflow-chamber, M. The conduit L and chamber M may be made in one piece with the basin, or they may be made separately and be secured thereto in any suitable manner.

The lower end ot the overflow-chamber is controlled by a valve, N, which is connected to one end ofa lever, O, which is arranged within the chamber and provided at the other end with afloat, I?. When the water rises sufficiently in this overow-chamber the oat P is raised and the Valve is lowered, so that it will open the aperture in the bottom ot' the chamber Whichitcontrols and permit the water to pass oft'. Whenever the water-level is lowered sufficiently the oat falls, thereby raising the valve N and causing it to close the aperture which it controls. The overflow-chamber is therefore always sealed with water, and noxious gases are precluded from escaping through it into the apartment where the water-closet is located. The Water which escapes from the overliow-chamber passes through a pipe or conduit, Q, to the chamber G.

This water-closet may have its outlet counected with any suitable trap, ifdesirable, and may have a vent-pipe, R, combined with its overow-chamber M.

It will be seen that by my invention I produce a water-closet from which all deposits will be thoroughly dischargethwhieh will be kept clean, and which will prevent noxious gases from escaping intotlle apartmentwhere it is located.

IWhat I claim as my invention, and desire to secure by Letters Patent, is-

l. In a Water-closet, the combination ofa basin, a valve-chamber connected thereto, a vertically-arranged valve-seat at the juncture of the basin and chamber, a slide-valve operating in conjunction with said seat to control the escape of the contents ot the basin, a guide for said valve, and a guideway parallel with said valve-seat, upon which said guide works, substantially as specified.

2. In a water-closet, the combination ofa basin, a valve-chamber connected thereto, a vertically-arranged valve-seat and slide-valve. for controlling the escape of the contents of the basin, a resistance-piece having` a sliding connection with the stem ot' said valve, and a spring arranged between said resistance-piece and valve, substantially as specined.

In a watercloset, the combination of the basin A, valve-chamber Gr, slide-valve F, arm K, rock-shaft D, and pull-rod B,substantially` as specied.

4. In a water-closet, the combination of the basin A, valve-chamberG, slide-valve F, with its tubular stem, the resistance-piece J, with its stem fitting in the tubular stein ofthe valve, and the spring I, substantially as specified.

5. In a watercloset, the combination of the basin A, valve-chamber G, slide-valve F, resistance-piece J, spring I, overlow-outlct A3, conduit L, overflowchamber M, valve N, lever O, and float P, all substantially as specified.
